Generation

Modus tollens is a valid form of logical reasoning that works backward from a false conclusion. It says: if you know that "if P, then Q" is true, and you observe that Q is actually false, then you can conclude that P must also be false. For example, if "If it's raining, then the ground is wet" is true, and you see the ground is not wet, you can validly conclude it's not raining. The key is that denying the consequence forces you to deny the condition that would have caused it.
